SHARP XE201 / 202 / 212 / 301-061113-1 CASH REGISTER TROUBLESHOOTING - FUSE FAILURE WHEN SOLENOID CABLE TOUCH THE DRAWYER

SHARP CASH REGISTER TROUBLESHOOTING - Fuse failure when Solenoid cable touch the drawyer - XE201 / 202 / 212 / 301-061113-1

FAULT: The fuse blew out when the solenoid cables touched the drawer

 Solenoid cables used to be twisted around the rib inside the lower cabinet. However, it sagged inside the drawer owing to the way it was twisted. The sagging solenoid cables touched the drawer when opening and closing the drawer. In order to avoid this problem, changed the solenoid cable arrangement inside the drawer. The solenoid cables shall be fixed by tie on the rib inside the lower cabinet.

The solenoid cables inside the drawer sagged owing to the variation of the cable fastening method. The solenoid cables touched the rear side of the drawer when opening and closing the drawer.

The fastening method of the solenoid cable at the drawer is as follows:

Before Change:

The solenoid cables were twisted around the front side of the rib of the lower drawer.

After Change:

   The solenoid cables are fixed with a tie to the rear side of the rib inside the lower cabinet.  Pulling the solenoid cables when fixed to the rear side of the rib with a tie not only avoids the cables sagging but gives space between the cables and the drawer.

   Fix the solenoid cables with a tie when replacing the drawers for repairs or maintenance.

BEFORE

The solenoid cables are twisted around the front side of the rib, inside the lower cabinet.

SERVICE MODE

Before turning the mode switch from the (SRV’) to (SRV), make sure the AC power cord is connected to the wall outlet; otherwise, the data on memory might be destroyed.

SRV. Reset (Program Loop Reset)

Used to return the machine back to its operational state after a lock-up has occurred.

• Unplug the AC cord from the wall outlet.
• Set the mode switch to (SRV’) position.
• Plugin the AC cord to the wall outlet.
• Turn to (SRV) position from (SRV’) position.

PROGRAM RESET ****

Master reset (All memory clear)

Used to clear all memory contents and return machine back to its initial settings. return keyboard back to default. for default keyboard layout.

• Unplug the AC cord from the wall outlet.
• Set the MODE switch to the (SRV’) position.
• Plugin the AC cord to the wall outlet.
• While holding down JOURNAL FEED key, turn to (SRV) position from (SRV’) position.

MASTER RESET ****

To start the diagnostic program, you must enter the following command.

3-digit test item number key in the SRV mode

The RAM must be operating properly to go into this mode. This is necessary because the control jumps to the program area in the SRV mode. A master reset must be performed before operating the ECR for the first time. After any option is installed, a program reset is required. When the master reset or program reset is performed, be sure to check the printout on the journal paper.

Master reset : Turn power on in the SRV’ mode and change it to the SRV mode with the PAPER FEED key pressed.

print : MASTER RESET ***

Program reset : Turn power on in the SRV’ mode and change it to the SRV mode.

print : PRG. RESET ***

With the SRV mode and the following test code entry, the test start

Cautions to be taken when removing the upper cabinet.

When removing the upper cabinet, first remove the printer cover and then remove the upper cabinet from the let side, as shown.

Cautions to be taken when installing the pop-up display connector cable.

Exercise care not to have the wrong direction of the pop-up display connector cable when connecting the cable to the Key I/F connector CN14.

When connecting the cable, make sure:

Sharp Cash Register XE A106 - Circuit Diagram - How to Reset  or- Initialize - Test Procedure

Reset Procedure or Initialization

Master reset: Clears all the memory and initializes each preset parameter

1. Turn off the power (Power OFF).
2. Let the ECR be without the memory back up battery.
3. Turn the mode switch to the others of Power-off position.
4. Turn on the power (Power ON). When the master rest is completed, the buzzer sounds intermittently three times.

5. Attach the memory back up battery to the ECR.  The master reset can also be accomplished in the following case.

Power OFF: Means disconnecting the AC power supply to the machine. (Specifically, unplugging the machine.)

Power ON: Means connecting the AC power to the ma-chine. (Specifically, plugging in the machine.)

[In case a power failure occurs when the machine has no battery installed, the master reset operation is automatically performed after the power has been restored.]
